Staking is the process of locking or committing crypto assets to help secure a Proof of Stake network, usually by running a validator or delegating to one. In exchange for contributing economic security and honest participation, stakers earn rewards.
The important mechanism is simple: a network needs honest validators to propose and attest blocks. Validators are incentivized to behave through rewards, and disincentivized from misbehavior through penalties that can include slashing.
Staking is not “interest” in the traditional banking sense. It is a security budget.
A Proof of Stake network needs an economically meaningful amount of capital at risk so that attacks become expensive. Staking creates that at-risk capital by requiring validators, or their delegators, to lock collateral.
The network then allocates rewards to validators that follow the rules, and it can penalize validators that go offline, censor, or attempt to corrupt consensus.
This mechanism-first framing matters because it explains why staking yields fluctuate. Rewards are a function of:
Solo staking means running the validator infrastructure directly and putting up the required stake on chains that have a minimum. On Ethereum, home staking is described as running an Ethereum node and depositing 32 ETH to activate a validator.
Solo staking generally offers maximal control, but it also requires operational competence. Uptime, key management, and safe upgrades matter.
Delegated staking is when a token holder delegates stake to validators, typically through a wallet interface. The validator performs the operational work, while the delegator retains ownership in a non-custodial model.
The mechanism is that delegators increase a validator’s effective stake, which can increase the validator’s block proposal probability or influence, depending on the chain’s design. Delegators then receive a share of rewards minus the validator’s commission.
Pooling exists because not everyone wants to run infrastructure or meet minimums. Liquid staking protocols go a step further by issuing a liquid receipt token that represents staked collateral.
For example, Lido explains liquid staking as depositing assets and receiving a token that accrues rewards and can be used elsewhere. Rocket Pool’s documentation frames a similar model for Ethereum with a decentralized operator design.
Liquid staking can improve capital efficiency because the receipt token can be used in DeFi, but it introduces smart contract and liquidity risks.
Restaking takes the core staking concept and reuses it to secure additional networks or services beyond the base chain.
Ethereum’s restaking explainer describes restaking as using staked assets to provide security to other services, while warning that it can amplify slashing and systemic risks.
The mechanism is that the same underlying stake becomes subject to additional rules and additional penalty conditions. This is often done through smart contracts and opt-in frameworks.
In simple terms:
Restaking frameworks typically create a marketplace where:
In staking, a delegator’s main risk is validator performance and protocol slashing. In restaking, operator selection becomes a bigger deal because operators are now running more software stacks and can be slashed by multiple systems.
A restaker should treat operator choice like a vendor selection problem: operational maturity, monitoring, incident response, and conservative AVS selection are central.
Restaking can therefore be viewed as “security reuse,” but also as “risk reuse.”
Restaking is not limited to one design.
These approaches differ in supported collateral, operator models, and slashing mechanics. That difference matters more than branding.
A conservative decision process in 2026 looks like this:
Sizing is the practical lever. Restaking does not require an all-in decision. It can be treated as a small, risk-budgeted allocation within a broader staking approach.
Staking is the core mechanism that secures Proof of Stake networks by putting capital at risk and rewarding honest validation. Restaking reuses that same stake to secure additional services by adding new slashing conditions, which can increase rewards but also increases complexity and systemic risk. In 2026, the difference between staking and restaking is best understood as a tradeoff between capital efficiency and risk surface, with the strongest outcomes coming from careful operator selection, conservative sizing, and a clear understanding of penalty mechanics.
